A Guide to Mass Shootings in America

Update May 24, 2014: America's latest mass shooting took place in Santa Barbara on Friday night. The New York Timesreports: "A college student who posted videos that documented his rage against women for rejecting him killed six people and wounded 13 others during a spasm of terror, the police said. He stabbed three men to death in his apartment and shot the others as he methodically opened fire on bystanders on the crowded streets of this small town." According to the LA Times, the guns he used—two Sig Sauer p226 model handguns and a Glock 34—were legally purchased from federally licensed dealers and were registered to the killer, who after a shootout with police ended his own life with a bullet to the head.
